This invention relates to certain improvements in associating mechanism for printing machines. A f

In prior United States Letters Patent No. 572,225 dated December 1, 1896, and No.

1,540,231, dated June 2, 1,925 bot-h 'to E. I.

Sheldon, there isdisclosed associating mechanism for associating a high speed web and` a a low speedV web or t sheet from different sources, certain cutting and collecting cylin-` ders being employed for associating a sheet withthe web andlcutting af sheet or sheets from the web f or association. In the mechanisms shown in these patents, five main cylinders are employed for effecting the cutting, association or collection of the products which the mechanisms are capacitated to produce. y

It is the especial object of the present invention to produce a mechanism yfor associating a high speed web, and a lowspeed sheet or associating two high speed webs in which the desired products can be obtained with a` less number of cylinders than used in the constructions referred to. s

1With this and other objects not specifically referred to in view, the invention consists in certain novel parts, arrangements and vcombinations which will be fully described in connection with the accompanying drawings and the novel features pointed out in the claims hereunto appended.

In these drawings,--

Figure 1 is a diagrammatic side elevation of so much of the folder end of a printing machine as is necessary for an understanding of the invention;

Figure 2 is a diagrammatic side View showing the arrangement of the parts and the web leads for associating a high speed web and a low speed sheet, and

Figure 8 is a diagrammatic side view showing the arrangement of the parts and the web leads when associating two high speed webs. y f

Referring now to these drawings and first to Figures 1 and 2, there is shown a construction in which a web is forwarded at high speed and a second web is forwarded at a lower speed. Sheets are cut from this low speed web and associated with a high speed web, this also then being severed, and in the particular construction illustrated, a yowv under atension roll 2 and a guide roll 3 toy a pair of cooperating cuttingv cylinders 4,' 5.

In the particular construction shown, the

cylinderei` is twice the diameter ofthe cyl-ik inder 5 and is"l driven at halfspeed. This cylinder; is supported ona'shaft Gand is pro-` vided vwith a 'pair of oppositely disposed cutting woods 7, 8, withwhich cooperates a out@ ting knife 9 on the cylinder 5. This latter cylinder' is supported on a shaft`10,the

shafts 6 and 10 beingsuitably mounted in,

the framing of themachine, indicated at 11.

The cylinder 4 is alsoprovidedwith sheet' taking( devices, shownl inthe form of pins 12, 13,'which act to take the low speed sheets.

The high speedweb is markedI-I and is led from the'printing mechanisimnot shown, over a tension' roll 14 and betweena pair of` forwarding rolls` 15, 16`7 lthe latter ofwhich is driven, these rolls being suitably mounted in the side frames 11, and from these rolls 15, 16 the full speed web is forwarded to a second pair of cutting and collecting cylinders 17, 18, suitably mounted on shafts 19, 2O supported in the side frames of the machine.

The cylinder 18 isprovided with a cutting wood 21 and the cylinder 17 is provided with a cutting knife 22. Each of the cylinders is provided with sets of sheet taking devices, shown as pins, the cylinder 17 having pins 23 and the rcylinder 18 having pins 24k. These cylinders 17, 18 are, it will be observed, half the diameter of the cylinder 4i. In the arrangement shown in Figures 1 and 2, a half speed sheet L', out from the web L by the cylindersll, 5, is to be associated between two full speed sheets from the web H, and the half speed sheet L is forwarded so as to be taken by the pins 23 on the cylinder 17 and brought up to full speed. In the particular construction for effecting this, the cylinder 4 is formed with out away or depressed portions 25, in advance of which are feeding segments 26 which cooperate with a roll 27 to feed the sheets forwardy passed between the bite of the cylinder 18 and the roll 30, so that there isno tendency ot' the associated halt speed sheet to slip bac-k into the line of cut.-

If desired, two full speed webs may be forwarded to the cylinders 17, 18 and col lected so as to produce a sixteen page product, and this Aarrangement is illustrated in Figure 3. When operating in this matter, the cylinders 1, 5 are idle and the two webs Ll and I-I are both run at high speed. r)The path of the web L is indicated in Figure 1, where it is shown as passing over the tensiony roll 2 under the guide roll 1 over a tension roll 33 to and between feeding rolls 15, 16, from which the two associated webs go to the cutting and collecting cylinders 17, 18. The parts of the machine may be driven in any suitable way, and gearing for doing this has been shown, but need not be described for an understanding of the invention.

While the invention has been shown in its preferred form and arrangement, it will be understood that certain variations and changes may be made in the specific constructions shown and described without departing from the invention as claimed in the appended claims.

` What I claim is:

1. The combination of means tor forward ing a high speed web, means t'or forwarding a web at a lower speed, a pair of cooperating cutting cylinders for severing a sheet from the lowspeed web, a second pair of cutting and associating` cylinders to which the high speed web and low speed sheet are forwarded for cutting a sheet from the high speed web, sheet holding means carried by the outer of the last pair ot cylinders for positively holding the sheet and web during the last cutting operation, and a folding delivery to which the associated sheets are delivered directly by the sheet holding means.

2. The combination of means Jfor forwarding a high speed web, means for forwarding a web at a lower speed, a pair of cooperating cutting cylinders for severing a sheet from the low speed web, a second pairof cutting and collecting cylinders to which the high speed web and low speed sheetare forwarded for cutting a sheet fromv the high speed web, pins carried by the last pair of cylinders for positively holding the sheet and web during the cutting operation, apressure roll cooperating with the outer of the last pair of cylinders between which and the cylinder the web is forwarded lby the pins, and a folding delivery to which the associated sheets are delivered.

In testimony whereof, I 'have hereunto set my hand.

LOUIS A. SCHMIDT.
